I don't have a part number or manufacturer but this is what I got from the Canadian Rotax dealer when I inquired about the regulator(s) on the IS Sport:
"They are a German made regulator, not Ducati. They do need cooling air; more so on the 30 amp, but the RV12 has good airflow in the cowl so it should not be a problem."

I should also mention that the sport comes standard with a 16 and 30 amp alternator, each have their own regulators.

Is the (apparently new) regulator used on the IS Sport compatible to retrofit to the older engines?

I have been using the alternative Amazon regulator for 100 hrs. with a small 2 inch wide fan blowing directly on the fins also. It is working great. I just piggybacked the hot wire for the fan to B+ wire on the regulator. It switches on and off with the master.

Hey Dave, which regulator is that from Amazon? Also, you might be interested to know this week I am doing a transition training for the newest owner of N588DF.
